Healthcare facilities follow filter guidelines of?

Healthcare facilities primarily follow filter guidelines from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). ASHRAE provides detailed standards and guidelines concerning ventilation and air quality in various settings, including healthcare. These guidelines are essential for maintaining appropriate indoor air quality and ensuring that the HVAC systems function effectively to minimize the risks of airborne contaminants, which is crucial in healthcare environments to protect patient health.

The other organizations listed contribute to the broader spectrum of health and safety in their respective areas but do not specifically focus on air filtration guidelines to the same extent. While the American Institute of Architects (AIA) deals with architectural design and standards, including some aspects of environmental quality, it does not provide the same level of detail on air filter specifications as ASHRAE. The CDC and OSHA both focus on public health and workplace safety, respectively, but their guidelines are more general and do not go into the technical specifications for air filtration systems found in healthcare settings. Thus, for knowledge pertaining specifically to filtration in healthcare facilities, ASHRAE's guidelines are the most applicable and critical.
